I'm using a RadListpicker control for a expense app, which is bound to a category table through Items source property (ObservableCollection). Everthing is well and the items are listed properly in the Listpicker (Popup).
Now, after I selected an item and also enter the rest of the expense record and hitting save button, the item saved within the record is actually the selected item -1 (previous one), for example, these Listpicker items:
if I select 3. Newspapers from the above list, then the saved item is 2. Magazines. Looks like I'm something missing here.
Here is my code:
If I select the first item 1. Books, nothing is saved at all and application closes itself.
Any hint on what might be wrong is appreciated.
